César Kawakami

Software engineer working on performance and scalability of distributed systems and web applications, plus infrastructure and developer tooling. Competitive programmer: silver medal for Brazil at the International Olympiad in Informatics 2007 and a top-70 finish at the ACM-ICPC World Finals (ITA, 2010-2011). LinkedIn-derived enrichment lists a current backend/software engineering role at Ameba (London) and past roles at Quadrature (Quant Developer), Facebook (engineer and intern), Geekie (lead software engineer) and LabOne Systems.

Notes10

• Quant employment verification: UNRESOLVED at seed stage. LinkedIn-derived enrichment lists 'Quant Developer at Quadrature' and 'Software Engineer Intern at Facebook' among past roles, and a Facebook profile lists 'Quant Developer, Quadrature, Apr 8 2019 - Present'; the caller-supplied lead dates the Quadrature role Apr 2019 - Jan 2024. Employment at Quadrature is therefore supported only by index/LinkedIn-derived data plus the person's own Facebook profile, not yet by an independent primary source; employer classification (Quadrature as a quantitative/systematic investment manager) also not yet verified from a primary source.Sep 17, 2026
• Quant employment verification (final): CONFIRMED. Role evidence: the subject's own LinkedIn profile reports 'Quant Developer at Quadrature' among past roles (accessed via the LinkedIn-derived index; a self-reported source, not independent). Employer classification: Quadrature is a systematic/quantitative trading hedge fund per its own website and Wikipedia. Current role: Ameba announced him as a Backend Engineer (London) in Sept 2024. The Facebook profile's 'Apr 8, 2019 - Present' Quadrature end-date conflicts with the caller lead's Jan 2024 end and with the Ameba start, so the Facebook 'Present' label is treated as stale.Sep 17, 2026
• The person's LinkedIn headline ('Software & Data Engineering, Engineering Leadership, Quant, Ameba AI') plus their IOI and ICPC record establish that the LinkedIn profile belongs to the same Cesar Kawakami who won IOI silver for Brazil in 2007; identity is corroborated across IOI stats, CPHOF and the LinkedIn-derived index, though the bridge between the competition record and the LinkedIn identity is the profile's own self-description.Sep 17, 2026
• Quadrature's own site describes it as 'a systematic trading firm' founded by programmers (2010) that builds 'automated trading systems' generating returns on proprietary capital; Wikipedia classifies it as a British quantitative finance hedge fund (founded 2008, founders Greg Skinner and Suneil Setiya). Two primary/encyclopedic sources independently confirm the employer is a quantitative/systematic trading firm, satisfying the requirement that the employer actually operates in quantitative finance.Sep 17, 2026
• Announced as Ameba's new Backend Engineer in London, focused on building backend systems.Sep 2024
• Represented Brazil at the International Olympiad in Informatics 2007 (Zagreb), winning a Silver medal with a score of 330/600, ranked 43rd overall; also a finalist at IOI 2006.Aug 22, 2007
• On a 2020 Olympiad prize-award video he is introduced as 'ex-olimpico, formado em Engenharia de Computacao pelo ITA' (former olympiad contestant, Computer Engineering graduate of ITA), confirming the IOI contestant and the ITA computer-engineering graduate are the same person.Dec 1, 2020
• Competed on the ITA 'Carteado' team at the ACM-ICPC World Finals in 2010 (59th) and 2011 (68th) with teammates Daniel Moreira and Guilherme Souza.May 30, 2011
• Earlier technology roles listed (index/LinkedIn-derived, not independently confirmed): Software Engineer at Facebook, Software Engineer Intern at Facebook, Lead Software Engineer at Geekie, and Intern at LabOne Systems S/A. The 'Software Engineer @ Geekie' identity is corroborated by the person's own 2048-5D game page and an old Medium bio.Sep 17, 2026
• Author of public code under GitHub username 'cesarkawakami' (github.com/cesarkawakami): repositories include 'tg' (Trabalho de Graduação, an ITA graduation project in Python/JavaScript), 'pandaviz' (data visualisation, used at an employer) and '2048-5D' (a 5-dimensional variants of 2048). The tg graduation project plus the Geekie credit on 2048-5D tie the account to the same ITA-trained Cesar Kawakami.Sep 17, 2026
• At ITA (Instituto Tecnologico de Aeronautica) around 2007-2010 while competing in the ICPC; studied Computer Engineering.Aug 2007
• Gave a lightning talk at PythonBrasil 2013 on surprising Python behaviours, later credited by Luciano Ramalho in Fluent Python; also spoke at PyCaxias 2014, described there as an ITA-trained engineer with experience at major technology companies.Oct 18, 2014
